The Viewer's drawing area displays dynamic maps that reflect the status of the system. The lines (used to represent pipes ) and the icons (used to represent assets and conditions) are called symbols; the conventions that govern symbols are referred to as symbology.

Certain condition symbols, such as event type or note indicator, provide tooltips indicating the symbol's meaning. For example, as shown in the illustration above, the Note symbol's hover text is Operator Note.

If configured, the Viewer will dim the parts of the model that are outside of the user's authority. In those sections, the user will not be able to operate or otherwise modify those assets without taking authority using the Authority tool (see “Taking Authority for Control Zones”).
